A history of International Headache Society grants and their impact on headache careers.

BACKGROUND: The International Headache Society has been offering multiple award opportunities for young researchers and clinicians for many years, with the aim of supporting the development of careers in headache science and medicine. METHODS: In order to assess the outcomes of the International Headache Society award grants, a questionnaire was sent to all previous recipients, investigating a series of aspects related to their work, both during and after award completion. RESULTS: Of 44 total questionnaires sent, 36 were returned. Eighty-one percent of the recipients reported to have remained in the headache field since the award, half of them held a current academic position and over three-quarters had stayed in contact with the host institution. The totality of questionnaire responders stated that the grant had had a significantly positive impact on their careers. CONCLUSIONS: The International Headache Society grants have assisted many young researchers in building an academic and clinical career in the field of headache, throughout the years.

Health technology assessment for the acute and preventive treatment of migraine: A position statement of the International Headache Society.

The Clinical Trials Subcommittee of the International Headache Society presents the first Health Technology Assessment for the Acute Treatment of Migraine Attacks and Prevention of Migraine. Health technology assessments are systematic evaluations of the properties, effects, and consequences of healthcare technologies; this position statement is designed to inform decision makers about access to and reimbursement for medications and devices for the acute and preventive treatment of migraine. This position statement extends beyond the already available guidelines on randomized controlled trials for migraine to incorporate real-world evidence and a synthetic approach for considering multiple data sources and modelling methods when assessing the value of migraine treatments.

My Migraine Voice survey: a global study of disease burden among individuals with migraine for whom preventive treatments have failed.

BACKGROUND: Migraine is associated with many debilitating symptoms that affect daily functioning. My Migraine Voice is a large global cross-sectional study aimed at understanding the full burden and impact of migraine directly from patients suffering from ≥4 monthly migraine days (MMDs) with a history of prophylactic treatment failure. METHODS: This study was conducted worldwide (31 countries across North and South Americas, Europe, the Middle East and Northern Africa, and the Asia-Pacific region) using an online survey administered to adults with migraine who reported ≥4 MMDs in the 3 months preceding survey administration, with pre-specified criteria of 90% having used preventive migraine treatment (80% with history of ≥1 treatment failure). Prophylactic treatment failure was defined as a reported change in preventive medication by individuals with migraine for any reason, at least once. RESULTS: In total, 11,266 individuals participated in the survey. Seventy-four percent of the participants reported spending time in darkness/isolation due to migraine (average: 19 h/month). While 85% of all respondents reported negative aspects of living with migraine (feeling helpless, depressed, not understood), sleeping difficulties (83%), and fear of the next attack (55%), 57% shared ≥1 positive aspect (learning to cope, becoming a stronger person). Forty-nine percent reported feeling limited in daily activities throughout all migraine phases. Migraine impact on professional, private, or social domains was reported by 87% of respondents (51% in all domains). In the previous 12 months, 38% of respondents had visited the emergency department (average: 3.3 visits), whereas 23% stayed in hospital overnight (average: 3.2 nights) due to migraine. CONCLUSIONS: The burden of migraine is substantial among this cohort of individuals with at least 4 migraine days per month and for whom at least 1 preventive migraine treatment had failed. Interestingly, respondents reported some positive aspects in their migraine journey; the greater resilience and strength brought on by coping with migraine suggests that if future treatments could address existing unmet needs, these individuals with migraine will be able to maximize their contribution to society.

Practice patterns and outcomes after stroke across countries at different economic levels (INTERSTROKE): an international observational study.

BACKGROUND: Stroke disproportionately affects people in low-income and middle-income countries. Although improvements in stroke care and outcomes have been reported in high-income countries, little is known about practice and outcomes in low and middle-income countries. We aimed to compare patterns of care available and their association with patient outcomes across countries at different economic levels. METHODS: We studied the patterns and effect of practice variations (ie, treatments used and access to services) among participants in the INTERSTROKE study, an international observational study that enrolled 13 447 stroke patients from 142 clinical sites in 32 countries between Jan 11, 2007, and Aug 8, 2015. We supplemented patient data with a questionnaire about health-care and stroke service facilities at all participating hospitals. Using univariate and multivariate regression analyses to account for patient casemix and service clustering, we estimated the association between services available, treatments given, and patient outcomes (death or dependency) at 1 month. FINDINGS: We obtained full information for 12 342 (92%) of 13 447 INTERSTROKE patients, from 108 hospitals in 28 countries; 2576 from 38 hospitals in ten high-income countries and 9766 from 70 hospitals in 18 low and middle-income countries. Patients in low-income and middle-income countries more often had severe strokes, intracerebral haemorrhage, poorer access to services, and used fewer investigations and treatments (p<0·0001) than those in high-income countries, although only differences in patient characteristics explained the poorer clinical outcomes in low and middle-income countries. However across all countries, irrespective of economic level, access to a stroke unit was associated with improved use of investigations and treatments, access to other rehabilitation services, and improved survival without severe dependency (odds ratio [OR] 1·29; 95% CI 1·14-1·44; all p<0·0001), which was independent of patient casemix characteristics and other measures of care. Use of acute antiplatelet treatment was associated with improved survival (1·39; 1·12-1·72) irrespective of other patient and service characteristics. INTERPRETATION: Evidence-based treatments, diagnostics, and stroke units were less commonly available or used in low and middle-income countries. Access to stroke units and appropriate use of antiplatelet treatment were associated with improved recovery. Improved care and facilities in low-income and middle-income countries are essential to improve outcomes. FUNDING: Chest, Heart and Stroke Scotland.

Cost-Effectiveness of Solitaire Stent Retriever Thrombectomy for Acute Ischemic Stroke: Results From the SWIFT-PRIME Trial (Solitaire With the Intention for Thrombectomy as Primary Endovascular Treatment for Acute Ischemic Stroke).

BACKGROUND AND PURPOSE: Clinical trials have demonstrated improved 90-day outcomes for patients with acute ischemic stroke treated with stent retriever thrombectomy plus tissue-type plasminogen activator (SST+tPA) compared with tPA. Previous studies suggested that this strategy may be cost-effective, but models were derived from pooled data and older assumptions. METHODS: In this prospective economic substudy conducted alongside the SWIFT-PRIME trial (Solitaire With the Intention for Thrombectomy as Primary Endovascular Treatment for Acute Ischemic Stroke), in-trial costs were measured for patients using detailed medical resource utilization and hospital billing data. Utility weights were assessed at 30 and 90 days using the EuroQol-5 dimension questionnaire. Post-trial costs and life-expectancy were estimated for each surviving patient using a model based on trial data and inputs derived from a contemporary cohort of ischemic stroke survivors. RESULTS: Index hospitalization costs were $17 183 per patient higher for SST+tPA than for tPA ($45 761 versus $28 578; P<0.001), driven by initial procedure costs. Between discharge and 90 days, costs were $4904 per patient lower for SST+tPA than for tPA ($11 270 versus $16 174; P=0.014); total 90-day costs remained higher with SST+tPA ($57 031 versus $44 752; P<0.001). Higher utility values for SST+tPA led to higher in-trial quality-adjusted life years (0.131 versus 0.105; P=0.005). In lifetime projections, SST+tPA was associated with substantial gains in quality-adjusted life years (6.79 versus 5.05), cost savings of $23 203 per patient and was economically dominant when compared with tPA in 90% of bootstrap replicates. CONCLUSIONS: Among patients with acute ischemic stroke enrolled in the SWIFT-PRIME trial, SST increased initial treatment costs, but was projected to improve quality-adjusted life-expectancy and reduce healthcare costs over a lifetime horizon compared with tPA.

Effect of apixaban on brain infarction and microbleeds: AVERROES-MRI assessment study.

BACKGROUND: Clinical and subclinical (covert) stroke is a cause of cognitive loss and functional impairment. In the AVERROES trial, we performed serial brain magnetic resonance imaging (MRI) scans in a subgroup to explore the effect of apixaban, compared with aspirin, on clinical and covert brain infarction and on microbleeds in patients with atrial fibrillation. METHODS: We performed brain MRI (T1, T2, fluid-attenuated inversion recovery, and T2* gradient echo sequences) in 1,180 at baseline and in 931 participants at follow-up. Mean interval from baseline to follow-up MRI scans was 1.0 year. The primary outcome was a composite of clinical ischemic stroke and covert embolic pattern infarction (defined as infarction >1.5 cm, cortical-based infarction, or new multiterritory infarction). Secondary outcomes included new MRI-detected brain infarcts and microbleeds and change in white matter hyperintensities. RESULTS: Baseline MRI scans revealed brain infarct(s) in 26.2% and microbleed(s) in 10.5%. The rate of the primary outcomes was 2.0% in the apixaban group and 3.3% in the aspirin group (hazard ratio [HR] 0.55; 0.27-1.14) from baseline to follow-up MRI scan (mean duration of follow-up: 1 year). In those who completed baseline and follow-up MRI scans, the rate of new infarction detected on MRI was 2.5% in the apixaban group and 2.2% in the aspirin group (HR 1.09; 0.47-2.52), but new infarcts were smaller in the apixaban group (P = .03). There was no difference in proportion with new microbleeds on follow-up MRI (HR 0.92; 0.53-1.60) between treatment groups. CONCLUSIONS: Apixaban treatment was associated with a nonsignificant trend toward reduction in the composite of clinical ischemic stroke and covert embolic-pattern infarction and did not increase the number of microbleeds in patients with atrial fibrillation compared with aspirin.

Cost-effectiveness analysis of non-invasive vagus nerve stimulation for the treatment of chronic cluster headache.

BACKGROUND: Cluster headache (CH) is a debilitating condition that is generally associated with substantial health care costs. Few therapies are approved for abortive or prophylactic treatment. Results from the prospective, randomised, open-label PREVA study suggested that adjunctive treatment with a novel non-invasive vagus nerve stimulation (nVNS) device led to decreased attack frequency and abortive medication use in patients with chronic CH (cCH). Herein, we evaluate whether nVNS is cost-effective compared with the current standard of care (SoC) for cCH. METHODS: A pharmacoeconomic model from the German statutory health insurance perspective was developed to estimate the 1-year cost-effectiveness of nVNS + SoC (versus SoC alone) using data from PREVA. Short-term treatment response data were taken from the clinical trial; longer-term response was modelled under scenarios of response maintenance, constant rate of response loss, and diminishing rate of response loss. Health-related quality of life was estimated by modelling EQ-5D™ data from PREVA; benefits were defined as quality-adjusted life-years (QALY). Abortive medication use data from PREVA, along with costs for the nVNS device and abortive therapies (i.e. intranasal zolmitriptan, subcutaneous sumatriptan, and inhaled oxygen), were used to assess health care costs in the German setting. RESULTS: The analysis resulted in mean expected yearly costs of €7096.69 for nVNS + SoC and €7511.35 for SoC alone and mean QALY of 0.607 for nVNS + SoC and 0.522 for SoC alone, suggesting that nVNS generates greater health benefits for lower overall cost. Abortive medication costs were 23 % lower with nVNS + SoC than with SoC alone. In the alternative scenarios (i.e. constant rate of response loss and diminishing rate of response loss), nVNS + SoC was more effective and cost saving than SoC alone. CONCLUSIONS: In all scenarios modelled from a German perspective, nVNS was cost-effective compared with current SoC, which suggests that adjunctive nVNS therapy provides economic benefits in the treatment of cCH. Notably, the current analysis included only costs associated with abortive treatments. Treatment with nVNS will likely promote further economic benefit when other potential sources of cost savings (e.g. reduced frequency of clinic visits) are considered.

Cost-effectiveness of an insertable cardiac monitor to detect atrial fibrillation in patients with cryptogenic stroke.

BACKGROUND AND AIMS: Documentation of atrial fibrillation is required to initiate oral anticoagulation therapy for recurrent stroke prevention. Atrial fibrillation often goes undetected with traditional electrocardiogram monitoring techniques. We evaluated whether atrial fibrillation detection using continuous long-term monitoring with an insertable cardiac monitor is cost-effective for preventing recurrent stroke in patients with cryptogenic stroke, in comparison to the standard of care. METHODS: A lifetime Markov model was developed to estimate the cost-effectiveness of insertable cardiac monitors from a UK National Health Service perspective using data from the randomized CRYSTAL-AF trial and other published literature. We also conducted scenario analyses (CHADS2 score) and probabilistic sensitivity analyses. All costs and benefits were discounted at 3.5%. RESULTS: Monitoring cryptogenic stroke patients with an insertable cardiac monitor was associated with fewer recurrent strokes and increased quality-adjusted life years compared to the standard of care (7.37 vs 7.22). Stroke-related costs were reduced in insertable cardiac monitor patients, but overall costs remained higher than the standard of care (£19,631 vs £17,045). The incremental cost-effectiveness ratio was £17,175 per quality-adjusted life years gained, compared to standard of care in the base-case scenario, which is below established quality-adjusted life years willingness-to-pay thresholds. When warfarin replaced non-vitamin-K oral anticoagulants as the main anticoagulation therapy, the incremental cost-effectiveness ratio was £13,296 per quality-adjusted life years gained. CONCLUSION: Insertable cardiac monitors are a cost-effective diagnostic tool for the prevention of recurrent stroke in patients with cryptogenic stroke. The cost-effectiveness results have relevance for the UK and across value-based healthcare systems that assess costs relative to outcomes.

Integrated care for chronic migraine patients: epidemiology, burden, diagnosis and treatment options.

Migraine is a common neurological disorder, characterised by severe headaches. Epidemiological studies in the USA and Europe have identified a subgroup of migraine patients with chronic migraine. Chronic migraine is defined as ≥15 headache days per month for ≥3 months, in which ≥8 days of the month meet criteria for migraine with or without aura, or respond to treatment specifically for migraine. Chronic migraine is associated with a higher burden of disease, more severe psychiatric comorbidity, greater use of healthcare resources, and higher overall costs than episodic migraine (<15 headache days per month). There is a strong need to improve diagnosis and therapeutic treatment of chronic migraine. Primary care physicians, as well as hospital-based physicians, are integral to the identification and treatment of these patients. The latest epidemiological data, as well as treatment options for chronic migraine patients, are reviewed here.

Practical implications of the migraine cardio- and cerebrovascular association: unmet needs of patients.

BACKGROUND: Numerous studies have described a relationship between migraine and stroke, and there is emerging evidence that migraine is also associated with cardiovascular disease. The combination of migraine and both cerebrovascular and cardiovascular disease has implications for therapy. METHODS: We conducted a review of the modifications in medical therapy in patients with comorbid migraine and cardio- and cerebrovascular disorders based on publications from the last 15 years. RESULTS: Some drugs are contraindicated to treat migraine attacks (ergots, triptans) or for migraine prevention in patients after transient ischemic attack (TIA)/ischemic stroke. Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) are contraindicated in patients with cerebral bleeding. Some drugs for the treatment of acute migraine attacks are contraindicated in patients with symptomatic coronary heart disease. CONCLUSIONS: Given the large number of patients with comorbid migraine and cardiovascular as well as cerebrovascular disease, there is an unmet need to treat these patients.

Addressing barriers to optimal oral anticoagulation use and persistence among patients with atrial fibrillation: Proceedings, Washington, DC, December 3-4, 2012.

Approximately half of patients with atrial fibrillation and with risk factors for stroke are not treated with oral anticoagulation (OAC), whether it be with vitamin K antagonists (VKAs) or novel OACs (NOACs); and of those treated, many discontinue treatment. Leaders from academia, government, industry, and professional societies convened in Washington, DC, on December 3-4, 2012, to identify barriers to optimal OAC use and adherence and to generate potential solutions. Participants identified a broad range of barriers, including knowledge gaps about stroke risk and the relative risks and benefits of anticoagulant therapies; lack of awareness regarding the potential use of NOAC agents for VKA-unsuitable patients; lack of recognition of expanded eligibility for OAC; lack of availability of reversal agents and the difficulty of anticoagulant effect monitoring for the NOACs; concerns with the bleeding risk of anticoagulant therapy, especially with the NOACs and particularly in the setting of dual antiplatelet therapy; suboptimal time in therapeutic range for VKA; and costs and insurance coverage. Proposed solutions were to define reasons for oral anticoagulant underuse classified in ways that can guide intervention and improve use, to increase awareness of stroke risk as well as the benefits and risks of OAC use via educational initiatives and feedback mechanisms, to better define the role of VKA in the current therapeutic era including eligibility and ineligibility for different anticoagulant therapies, to identify NOAC reversal agents and monitoring strategies and make knowledge regarding their use publicly available, to minimize the duration of dual antiplatelet therapy and concomitant OAC where possible, to improve time in therapeutic range for VKA, to leverage observational data sets to refine understanding of OAC use and outcomes in general practice, and to better align health system incentives.

Occipital nerve stimulation for intractable chronic cluster headache or migraine: a critical analysis of direct treatment costs and complications.

BACKGROUND: Occipital nerve stimulation (ONS) has been shown to be effective for selected patients with intractable headache disorders. We performed a prospective critical evaluation of complications and direct treatment costs. METHODS: Twenty-seven patients with chronic cluster headache (CCH, N = 24) or chronic migraine (CM, N = 3) underwent a trial phase with bilateral ONS and subsequent implantation of a permanent generator (IPG), if responsive to treatment according to predefined criteria. Procedural and long-term complications as well as direct treatment costs of neuromodulation therapy of ONS were recorded over a mean follow-up period of 20 months (range 5-47 months). RESULTS: Twenty-five of 27 patients (93%) responded to treatment. Twenty-one complications in 14 patients were identified, necessitating reoperation in 13 cases. Overall treatment costs were €761,043, including hardware-related costs of €506,019, costs for primary hospital care of €210,496, and complications related to hospitalization costs of €44,528. This results in a per case-based cost of €9445 for hospitalization and €18,741 for hardware costs, totaling €28,186. CONCLUSION: ONS for treatment of refractory CCH and CM is a cost-intensive treatment option with a significant complication rate. Nevertheless, patients with refractory primary headache disorders may experience substantial relief of pain attacks, and headache days, respectively.

Treatment costs and indirect costs of cluster headache: A health economics analysis.

BACKGROUND: Cluster headache (CH) is the most frequent trigemino-autonomic cephalgia. CH can manifest as episodic (eCH) or chronic cluster headache (cCH) causing significant burden of disease and requiring attack therapy and prophylactic treatment. METHODS: Treatment costs (direct costs) due to healthcare utilisation, as well as costs caused by disability and reduction in earning capacity (indirect costs), were obtained using a questionnaire in CH patients treated in a tertiary headache centre based at the University Duisburg-Essen over a 6-month period. RESULTS: A total 179 patients (72 cCH, 107 eCH) were included. Mean attack frequency was 3.5 ± 2.5 per day. Mean direct and indirect costs for one person were €5963 in the 6-month period. Direct costs were positively correlated with attack frequency (r = 0.467, p < 0.001). Burden of disease measured with HIT-6 showed a significant correlation with attack frequency (r = 0.467, p < 0.001). Twenty-four (13.4%) of the participants were disabled and not able to work. CONCLUSION: CH leads to major socioeconomic impact on patients as well as society due to direct healthcare costs and indirect costs caused by loss of working capacity.

Cost-utility analysis of eprosartan compared to enalapril in primary prevention and nitrendipine in secondary prevention in Europe--the HEALTH model.

OBJECTIVE: To investigate the cost-utility of eprosartan versus enalapril (primary prevention) and versus nitrendipine (secondary prevention) on the basis of head-to-head evidence from randomized controlled trials. METHODS: The HEALTH model (Health Economic Assessment of Life with Teveten for Hypertension) is an object-oriented probabilistic Monte Carlo simulation model. It combines a Framingham-based risk calculation with a systolic blood pressure approach to estimate the relative risk reduction of cardiovascular and cerebrovascular events based on recent meta-analyses. In secondary prevention, an additional risk reduction is modeled for eprosartan according to the results of the MOSES study ("Morbidity and Mortality after Stroke--Eprosartan Compared to Nitrendipine for Secondary Prevention"). Costs and utilities were derived from published estimates considering European country-specific health-care payer perspectives. RESULTS: Comparing eprosartan to enalapril in a primary prevention setting the mean costs per quality adjusted life year (QALY) gained were highest in Germany (Euro 24,036) followed by Belgium (Euro 17,863), the UK (Euro 16,364), Norway (Euro 13,834), Sweden (Euro 11,691) and Spain (Euro 7918). In a secondary prevention setting (eprosartan vs. nitrendipine) the highest costs per QALY gained have been observed in Germany (Euro 9136) followed by the UK (Euro 6008), Norway (Euro 1695), Sweden (Euro 907), Spain (Euro -2054) and Belgium (Euro -5767). CONCLUSIONS: Considering a Euro 30,000 willingness-to-pay threshold per QALY gained, eprosartan is cost-effective as compared to enalapril in primary prevention (patients >or=50 years old and a systolic blood pressure >or=160 mm Hg) and cost-effective as compared to nitrendipine in secondary prevention (all investigated patients).

Development and validation of a pharmacy migraine questionnaire to assess suitability for treatment with a triptan.

A questionnaire (Migraine Questionnaire; MQ) was developed to help pharmacists identify consumers with migraine suitable for non-prescription treatment with a triptan. Adults, who knew or thought that they had migraine, participated in three, sequential, community-based studies to validate the MQ. Overall, 1,353 subjects completed independent assessments with a pharmacist and a clinician (reference standard). The accuracy of the pharmacist assessment of suitability for a triptan was compared with the clinician assessment. Clinicians using their standard practice determined that triptan therapy was suitable in 76.8% of cases compared with 48.8% for pharmacists using the MQ. The lack of concordance between pharmacists and clinicians in the false-positive cases (n = 113 of 660 subjects considered suitable for triptan by the pharmacists) usually related to headache diagnosis (57.5%), not safety aspects. The MQ is an effective tool for pharmacists to guide appropriate recommendation of a non-prescription triptan for migraine.

Outcome parameters for trials in atrial fibrillation: executive summary.

Atrial fibrillation (AF), the most common atrial arrhythmia, has a complex aetiology and causes relevant morbidity and mortality due to different mechanisms, including but not limited to stroke, heart failure, and tachy- or bradyarrhythmia. Current therapeutic options (rate control, rhythm control, antithrombotic therapy, 'upstream therapy') only prevent a part of this burden of disease. Several new treatment modalities are therefore under evaluation in controlled trials. Given the multifold clinical consequences of AF, trials in AF patients should assess the effect of therapy in each of the main outcome domains. This paper describes an expert consensus of required outcome parameters in seven relevant outcome domains, namely death, stroke, symptoms and quality of life, rhythm, left ventricular function, cost, and emerging outcome parameters. In addition to these 'requirements' for outcome assessment in AF trials, further, more detailed outcome parameters are described. In addition to a careful selection of a relevant primary outcome parameter, coverage of outcomes in all major domains of AF-related morbidity and mortality is desirable for any clinical trial in AF.

Association between disability measures and healthcare costs after initial treatment for acute stroke.

BACKGROUND AND PURPOSE: The distribution of 3-month modified Rankin scale (mRS) scores has been used as an outcome measure in acute stroke trials. We hypothesized that hospitalization and institutional care home stays within the first 90 days after stroke should be closely related to 90-day mRS, that each higher mRS category will reflect incremental cost, and that resource use may be less clearly linked to the National Institutes of Health Stroke Scale (NIHSS) or Barthel index. METHODS: We examined resource use data from the GAIN International trial comparing 90-day mRS with total length of stay in hospital or other institutions during the first 90 days. We repeated analyses using NIHSS and Barthel index scores. Relationships were examined by analysis of variance (ANOVA) with Bonferroni contrasts of adjacent score categories. Estimated costs were based on published Scottish figures. RESULTS: We had full data from 1717 patients. Length of stay was strongly associated with final mRS (P<0.0001). Each mRS increment from 0 to 1-2 to 3-4 was significant (mean length of stay: 17, 25, 44, 58, 79 days; P<0.0005). Ninety-five percent confidence limits for estimated costs ( pound) rose incrementally: 2493 to 3412, 3369 to 4479, 5784 to 7008, 7300 to 8512, 10 095 to 11 141, 11 772 to 13 560, and 2623 to 3321 for mRS 0 to 5 and dead, respectively. Weaker relationships existed with Barthel and NIHSS. CONCLUSIONS: Each mRS category reflects different average length of hospital and institutional stay. Associated costs are meaningfully different across the full range of mRS outcomes. Analysis of the full distribution of mRS scores is appropriate for interpretation of treatment effects after acute stroke and more informative than Barthel or NIHSS end points.

[Evaluation and performance-based budgeting of the Halle University Outpatient Clinics]. / Leistungsorientierte Budgetierung der Ambulanzen des Universitätsklinikums Halle.

The Medical School of Halle has fundamentally restructured the university hospital's outpatient clinics. This required a detailed analysis of costs, income, and organization, as well as a prospective survey. In a representative month, more than 15,000 consultations were documented. Of all visits, 9% were part of clinical trials, and 19% part of the teaching and training of students and young doctors. 52% of all appointments were follow-up consultations. Operative and non-operative specialties as well as general and specialist consultations displayed considerable differences. Clinics with a high rate of follow-up consultations attended to fewer trial participants than others. In comparison to a district covered by statutory health insurance physicians the proportion of oncological diagnoses in the university hospital outpatient clinics was markedly higher. Costs for the different specialties' outpatient clinics varied significantly; a positive correlation was noted between the percentage of oncological diagnoses and secondary costs. The outpatient clinics' commitment to the outpatient care of cancer patients exceeds by far the scientific focus of the Medical School of Halle and contributes greatly to the provision of regional health care services. Within the scope of the project, the annual faculty allowances to the outpatient clinics were reduced by 25%. Since 2003, 60% of the remaining total allowances have been made available to the departments as an output-related grant. It was crucial to the acceptance of this budgeting that the expenses saved were dedicated to the support of young scientists, that the budgeting was comprehensible and that scientific achievements and in future also high quality teaching will continue to help regain some of the money "lost".
